I dont really understand what the number of decimals is related to the price?! Can you explain this by chance a little further (to someone that is not a big fan of math). Thanks in advance!

Most of the cryptocoins have eight decimal digits. For instance, Bitcoin can be divided to 0.00000001. ADA has six digits, so can be divided to 0.000001. To make them "comparable" in pure coin supply terms, you have to divide ADA coin supply by 100 to account for the two less digits. So max cap 45.000.000.000 would be camparable to a 450 million eight digits coin.

In this way, the current price around $0.118185 for 25 billion ADA would be comparable to $11.8185 for an eight digits coin.
